Bidirectional and double-R pipe bending machine with jacking and upsetting function

Abstract

The invention discloses a bidirectional and double-R pipe bending machine with a jacking and upsetting function. The bidirectional and double-R pipe bending machine comprises a supporting base and a pipe bending machine tool which is arranged above the supporting base and connected with the supporting base in a sliding manner. A machine tool transverse moving device driving the pipe bending machine tool to slide on the supporting base is arranged on one side of the pipe bending machine tool. The pipe bending machine tool comprises a pipe bending device. The pipe bending device is sequentiallyprovided with a jacking and upsetting clamping device, a pipe carrier roller device, a plate wrinkling preventing device and a bidirectional double-R pipe bending die device in the pipe conveying direction. The jacking and upsetting clamping device is used for providing axial jacking and upsetting force during pipe bending so as to prevent the outer wall of a bend from being thinned, and the jacking and upsetting clamping device comprises a rotation type clamping mechanism and an axial jacking and upsetting mechanism. The pipe carrier roller device is used for supporting a pipe. By means of the bidirectional and double-R pipe bending machine with a jacking and upsetting function, the pipe bending device is arranged, so that the problem of thinning of the outer wall of the bend in the pipebending process is solved, and the problem that the inner side of the bend is likely to be wrinkled during left and right bidirectional thin-wall small R pipe bending is solved.

Description

technical field [0001] The invention relates to the technical field of pipe benders, in particular to a bidirectional double R pipe bender with top piers. Background technique [0002] The serpentine tube bending machine is mainly used in boiler, metallurgy, chemical industry and other industries. Equipped with fixed-length tube delivery equipment, it can realize multi-head continuous bending of convective heating surface tubes such as economizers, superheaters, and reheaters, including CNC small R Top heading bidirectional double R pipe bender and roll bending bidirectional double R pipe bender and other specifications and models. However, the existing pipe bending machines often have the thinning of the outer wall of the elbow when bending the pipe, and the problem that the inner side of the elbow is easy to wrinkle when the left and right bidirectional thin-walled small R pipes are bent, and the existing double The problem that the double R tower type pipe bending die do...
